TDA8559T Low voltage stereo headphone amplifier
General description for TDA8559T:
The TDA8559T is a stereo amplifier that operates over a wide supply voltage range from 1.9 V to 30 V and consumes a very low quiescent current. This makes it suitable for battery fed applications (2 × 1.5 V cells). Because of an internal voltage buffer, this device can be used with or without a capacitor connected in series with the load. It can be applied as a headphone amplifier, but also as a mono amplifier with a small speaker (25 Ω), or as a line driver in mains applications.
Features for TDA8559T:
- Operating voltage from 1.9 V to 30 V
- Very low quiescent current
- Low distortion
- Few external components
- Differential inputs
- Usable as a mono amplifier in Bridge-Tied Load (BTL) or stereo Single-Ended (SE)
- Single-ended mode without loudspeaker capacitor
- Mute and Standby mode
- Short-circuit proof to ground, to supply voltage (< 10 V) and across load
- No switch on or switch off clicks
- SD protected on all pins
Applications for TDA8559T:
- Portable telephones
- MP3 players
- Portable audio
- Mains fed equipment
